I'm looking for an upper that I can shoot handloads into 1" or better at 100 yds. Just about every AR-15 shoots 1.5+ MOA. I can get that with my Mini-14. I'd like to do better for small varmints and coyotes. If it will keep a 60+gr bullet into 2"@200 yds I will consider it. Oly K-16, RRA predator, DPMS Sweet 16, etc. are on my list of preferred. Anything proven to be sub MOA is good. I can trade an SAA Base model complete upper with Nickel Boron BCG & dragon
